The top Intel Core Ultra Series 4 “Nova Lake-S” desktop processor model, which comes with a total core-count of 56 and implements a big last-level cache (bLLC), could pull an astonishing 700 W in maxed out loads with power limits removed, kopite7kimi reports. The chip has a core-configuration of 16 P-cores, 32 E-cores, and 4 low-power island E-cores. For reference, a current Core Ultra 9 285K with Extreme power profile can pull up to 490 W PL4 in short bursts.
In related news, leaks by Jaykihn shed light on the way clock speeds of the various CPU core types are handled. The base frequency affects the clock speeds of P-cores and E-cores located in the Compute complex, but not those of the low-power island E-cores. “Nova Lake-S” will be Intel’s first desktop processors to implement low-power islands, allowing the processor to clock-gate almost the entire compute complex when the PC is idling.
